The Rural Voice, 1987-03, Page 23depth and furrows to a depth of 4 inches. Combine soil cores from ridges and furrows in equal numbers to make up the composite. University of Minnesota: In chisel plow, offset disk, and no -till, continue to take soil samples from 0 to 6 inches for P and K analyses. A shallow sam- ple from 0 to 2 inches may be needed for soil surface pH considerations. In ridge -till, take samples after planting, but before cultivation. For other times of the year, sample half- way up the ridge only. University of Kentucky: Sample to a 4 -inch depth in no -till. Purdue University: In no -till fields when N is injected below the surface, sample at 2 depths, 0 to 4 inches and 4 to 8 inches. The same applies for all reduced -till fields whether N is applied surface or sub -surface. In no -till when N is surface -applied, sample 0 to 2 in- ches and 2 to 8 inches. University of Illinois: A compo- site soil sample needs to be taken for each 3 to 4 -acre portion to a depth of 7 inches. A 0 to 2 -inch sample will help to pinpoint pH changes. As far as I'm concerned, there is a good deal of worrying about nutrient stratification for nothing. If you have three to five years of soil test and tissue test histories as well as past fertilizer use and crop yields before you start into conservation tillage and/or sub -surface banding of nutrients, your worries are half solved. If you pick a good program (I like the University of Wisconsin's) and deal with a compe- tent, experienced agronomist, you shouldn't have a worry in the world — that is, with the exception of drought, hail, flood, frost, and poor markets!O Mervyn Erb Agronomist ADVERTISING CORRECTION for CROFT AGRITIL CORP.
